  • Enhanced, seamless information flow within and between plant systems and business applications
  • Automated instantaneous reporting
  • Integrated information from plant data and business systems
  • Aids Measurement of Key Performance Indicators (KPIs)
  • Automatic database configuration and updating
  • Rapid and simple implementation
  • Industry standard Microsoft Windows operating system

Exaquantum has a very clear business-directed focus to integrate data across an enterprise, delivering operational information to the whole business. Exaquantum provides industry with powerful plant information management, covering both business and process control domains. It eliminates the gap between business systems and process control by integrating information to meet complex business requirements.

Exaquantum provides the basis for Plant Information Management Systems (PIMS) and Manufacturing Execution Systems (MES) that delivers business benefits to users in the Hydrocarbons, Pulp & Paper, Power & Utilities, Chemicals, Pharmaceuticals, Food & Drink, Manufacturing and other continuous or batch processing industries. This is achieved by integrating data from all facets of the business, then transforming these into usable, high-value business information, which can be used as part of the enterprise's vital decision support tool set.

Yokogawa's LIMS Data Exchange (Exaquantum/LDX) enables data from LIMS packages to be reported to Exaquantum users throughout the plant. LDX stores LIMS data supplied by LIMS packages (such as LabWare LIMS) into Exaquantum tags. Data is passed into Exaquantum tags whenever a test result is released by an authorised laboratory person. Quality data can then be combined with Process data providing much richer trends, reports and KPIs.

Exaquantum/LDX
 

Exaquantum/VPN enables business systems to extract data from the process environment, without compromising security. Exaquantum/VPN provides a secure and controlled connection, typically through a firewall, initiated from an OPC server (running as a service) to the Exaquantum system (OPC client). Security is ensured by utilizing a VPN Protocol (for example, PPTP, L2TP over IPSec, or any other VPN protocol that may terminate on the Exaquantum Server) to provide an encrypted link.

Exaquantum/VPN

 

Exaquantum Historical Data Manager allows Exaquantum to continually collect process data from an OPC HDA Server(s) into an Exaquantum Real-Time database. Normally data received from an OPC HDA server is stored directly into the Exaquantum Historical Database. By storing the data into the Real-Time database, graphical screens, calculations and aggregations will be updated.

Exaquantum/HDM

 

1.1 Introduction

Exaquantum/FDM reads CSV formatted files containing process data from a specified File folder(s) and then transfers the data into the Exaquantum Historian.

1.2 Capabilities

The Read Interval at which Exaquantum/FDM checks each file folder for the presence of new files is configurable. On each folder access, all CSV files present in the folder are processed up to a configured maximum number of files for that Read Interval. Files continue to be processed at each successive Read Interval until no further files remain in the File folder.

After processing in file creation order, files with no errors are moved to a specified Archive files folder while files which cause errors during the read are moved to a specified Error files folder. The maximum number of files kept in each folder may be specified to prevent unlimited use of disk space.

File names written to a File folder must be unique. If a file with the same name already exists in the Error or Archive files folder then the newly-processed file is simply deleted. If an error occurs while moving a file to the Archive or Error files folder an error is logged and the file is deleted. During file processing the status (success or error) of the processing is logged to the Windows Event log.

1.3 CSV File Format

The information provided for each row in each CSV file is:

  1. Tag Name (Mandatory). This is the Exaquantum Tag (data point) name.
  2. Value (Mandatory). This is the Tag value.
  3. Quality (Optional). If present, the Quality will be stored with the Tag Value. The Quality definitions are configurable for instance Good Quality = 1 or Good Quality = "Good".
  4. Timestamp (Optional). A Timestamp for the Tag Value can be entered otherwise the current time when the CSV file is read will be used. The timestamp format is configurable for instance 'ddMMyyyy HHmm' or 'ddMMyyyy HH:mm:ss'.

The following is an example of a CSV file containing two rows.

704F000101.PV,15042013 1400,56.1,1
704F000102.SV,15042013 1400,55,0
704F000103.MODE,15042013 1400,"This is a text string",1

Where
Column 1 = Tag Name
Column 2 = Data time stamp using the format 'ddMMyyyy HHmm'
Column 3 = Data Value
Column 4 = Data Quality (0 = Bad Quality, 1 = Good Quality, 2 = Uncertain Quality)

Emails can be sent from Exaquantum

  • From filtered Alarms & Events
  • From an Exaquantum Calculated Tag
  • At the end of each Exaquantum Tag Aggregation period

An email can be sent to one or more email addresses

Alarm & Events

Every Alarm & Event received by Exaquantum can have one or more filters configured for one or more fields resulting in an email being sent if a match occurs
